NAME

pymoctool - manipulate Multi-Order Coverage maps

SYNOPSIS

pymoctool [INPUT] [COMMAND [FILE]] [--output OUTPUT]

DESCRIPTION

pymoctool can be used to manupulate Multi-Order Coverage (MOC) tools for the Virtual Observatory. It is a command-line tool and can handle files encoded as FITS, JSON, or ASCII. The tool maintains builds up a MOC stack using union, intersection and subtraction, with the pipeline processed in the order it is passed on the command-line.

Internally pymoctool uses and exposes the the PyMOC library found in the python-pymoc Debian package.

COMMANDS

--catalog coords.txt [order NN] [radius NN]

Render a circles using the flood-fill method on top of the MOC stack. The input text file should be whitespace records containing either RA+Dec pairs or Lat+Lon pairs.

--help, -h

Show top-level help

--id

Set new identifier for MOC stack

--info, -i

Display information about the MOC stack

--intersection

Intersect another MOC with the existing MOC stack

--name

Set new name for the MOC stack

--normalize 0-29

Set the maximum depth order of a MOC in the range 0-29

--output, -o

Output filename MOC

--plot

Project and render the MOC as a flattened all-sky map

--subtract

Subtract the a MOC from the existing MOC stack

--version

Show the backend PyMOC library version number

Detailed help for individuals commands can be found with pymoctool --help COMMAND

EXAMPLES

pymoctool foo.fits --output foo.json bar.txt --output both.fits

Load foo.fits then convert and the save a copy to foo.json perform a union merge with a text-format MOC called bar.txt and save the result both.fits
